内旋风式无瞬心包络加工螺杆数控铣削技术

CNC Milling for Screw with Inner Whirlwind Non - Instant Center Envelope

文章针对大型截面廓形为凸形复杂螺杆螺旋曲面的加工,提出了一种高效、高精度、实用的内旋风式 无瞬心包络数控铣削技术,并论述了其基本原理及其刀具轨迹的计算方法。

This paper introduces the machining principle of the inner whirlwind non - instant center envelope which is of high - efficiency, high - precision and practical. At the same time, it discusses the approach to calculate tool - path in machining complex - convex screw of big section with inner whirlwind non - instant center enveloped method.
